It is important to compare the cleanliness of remelted and recycled aluminum with primary metal. Such a metal might contain a higher level of inclusions than primary aluminum. The reason is the paint, oil, grease, etc. covering parts of the scrap metal. Thus the content of oxides and carbides could be a problem. Perhaps especially carbides could cause problems due to the presence of the hydrocarbons. Three campaigns were conducted, in 1993, 1994, and in 1995. The same number of charges were studied from the batch and semi-continuous units. In the first campaign inclusions were studied, in the second inclusions and hydrogen were investigated while in the last campaign only hydrogen was measured.
